Numbers that are divisible by 2 are called Even numbers(ending with 0,2,4,6,8), while numbers that are not divisible by 2 are called odd numbers(which are ending with 1,3,5,7,9)
Example:
Input: 5
Output:
Sum of Odd Numbers present from number 1 to 5 =1+3+5=9
Sum of Even Numbers present from number 1 to 5=2+4=6
class SumofOddNumbers {
public static void main(String args[] ) {
int n,oddSum=0;
Scanner sc=new Scanner(System.in);
System.out.println(“Enter the number”);
n=sc.nextInt();
for(int i=1;i<=n;i++){
if(i%2!=0){
oddSum=oddSum+i;
}
}
System.out.println(“Sum of odd numbers upto” +n+“=”+oddSum);
}
}
